This is all now with 2.6.12-rc6, with Jens Axboe's patch for SATA suspend (as the machine has a SATA interface and uses ata_piix). I tried Shaohua's S3 "test tool" and gave it a shot -- with it I'm able to go through a suspend/resume cycle with no problems. Without it, the machine locks up after unsuspend (after we're back in kernel code) with the nvidia driver loaded, and is otherwise unstable without the nvidia driver loaded. In particular, the ethernet device is completely screwed after coming out of unsuspend. lspci shows (after unsuspend): 02:00.0 Ethernet controller: Broadcom Corporation NetXtreme BCM5751 Gigabit Ethernet PCI Express (rev ff) (prog-if ff) !!! Unknown header type 7f and lspci -x reports the entire config space coming back as 0xff. This does not happen with the fake-S3 test patch. The device tree, as reported by lspci -t for this device looks like: -[0000:00]-+-1c.0-[0000:02]----00.0 00:1c.0 PCI bridge: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) PCI Express Port 1 (rev 03) The other device that's not coming up right is the video hardware, and it's on the "PCI Express Root Port". All the PCI (not PCI Express) devices going through a PCI bridge seem to come back through fine, as do USB and other bits. Just the two devices on the PCI Express bus seem screwed up post-resume, though lspci is able to read the nvidia device's config space post-resume. Any ideas where to start looking for a cause? I figure fixing the tg3 issue should help track down the overall problem. Thanks, - Vlad ------------------------------------------------------- This SF.Net email is sponsored by: NEC IT Guy Games.
